Thirty coconut trees were planted along Tran Phu Road, the most beautiful coastal road in Khanh Hoa province. Tree planting is an annual activity of the sea festival, aiming to tighten the friendship between Khanh Hoa and other cities in the world, especially with sister cities such as Incheon (the Republic of Korea), and Lorient (Morbihan, France). 

It also sends a message that Nha Trang needs more green trees to protect the environment in order to build a better and friendly city.
